# Optimizely Feature Experimentation (Full Stack) Enhancements

We have revamped our Optimizely Feature Experimentation (formerly Full Stack) integration. With these enhancements, you can:

- Set up and configure your Optimizely destination in no time by leveraging the enhanced UI.
- Send events to Optimizely via [cloud mode](https://www.rudderstack.com/docs/destinations/streaming-destinations/optimizely-feature-experimentation/cloud-mode/).
- Map custom RudderStack events and attributes to specific Optimizely fields using our intuitive mapping interface or the newly-introduced JSON mapper. If you do not specify these mappings, RudderStack sends the event name to Optimizely by default.

See our [Optimizely Feature Experimentation documentation]({{< ref "destinations/streaming-destinations/optimizely-feature-experimentation/_index.md" >}}) to get started.
